Due to the need to dispose of rainwater from Eko-IZ Nemetin, which extends to approximately 609.000 m², which does not include approx. 50 ha that are currently not infrastructurally equipped and are the subject of development of the zone, a complete solution of precipitation drainage has been designed in accordance with the requirements of public-law bodies. As part of the construction, pouring channels will be arranged, built facilities for proper functioning and management (watering structures, prefigures, etc.), and in the total length of 6.071 m' closed and open channels.
